Hi Victor,

>I'm sending output via ?/?? commands to the printer. The output should always go to LPT1 so I issue SET PRINTER TO LPT1. The problem is that VFP ignores this and send any output to the default printer. Is that a known bug?

VFP sends output to a printer, not a port. Can you install a "Generic/Text only" printer driver, connect that one to LPT1 and then use SET PRINTER TO the generic printer driver?
